At present, under the grim situation of the coal mine security in our country, the development ofcoal mine safety are faced with both opportunities and challenges, and it has great practicalsignificance to study the risk evaluation of coal mine safety in our country. In order to effectivelydeal with the fuzzy information in the process of risk assessment, aiming at the problems andresearch hotspots existing in the coal mine safety risk fuzzy evaluation, this paper carry outsystematic study on the fuzzy evaluation technique and application of coal mine safety risk. First ofall, this paper propose three-dimensional parametric evaluation coal mine safety fuzzy riskdefinition that include the risk damage degree, identifiable difficulty and dangerous trend, and buildthree-dimensional coal mine safety risk evaluation index system. Secondly, the qualitative indexesare measured by linguistic value in this paper, and put forward the corresponding fuzzy numberscale and language value integration method, as well as a variety of computing method on fuzzyweight based on AHP and entropy. Finally, build a comprehensive evaluation model of coal minesafety risk based on the integration operator and Fuzzy TOPSIS method, and analyze theapplication of the model.
